To make negative sentences in Mandarin, we mostly use two words: “不” (bù) and “没” (méi). Each word has its own special use.

1. Using "不" (bù):

   • We say “不” when we want to express that something is not happening now or in the future.
   • For example:
     • 我不去 (Wǒ bù qù) means "I am not going."

2. Using "没" (méi):

   • We use “没” when talking about something that didn't happen in the past or to say something is not there.
   • For example:
     • 我没去 (Wǒ méi qù) means "I did not go."

3. Practice:

   • Listening & Speaking: Try listening to conversations that use “不” and “没.” This will help you understand better.
   • Reading: Find articles that include both words so you can see how they are used.
   • Writing: Write your own sentences with “不” and “没” to practice making sentences.

Remember to pay attention to how the sentences are put together. This will help you understand them better!
